近年来由于影像学的发展和进步,使骨肉瘤的外科治疗取得了很大进展,保留肢体的根治性局部切除,正在取代传统的截肢术,而其局部复发率均在5％左右。在众多的影像学检查中,如何选择应用,是临床医师面临的新课题,这关系到临床的诊断和治疗。许多学者强调影像学检查的梯次性。虽然X片能显示骨肉瘤的部位,体积、骨破坏和成骨反应的有无,但不能确定骨髓腔的侵袭程度。而同位素扫描则能
In recent years, due to the development and progress of imaging, great progress has been made in the surgical treatment of osteosarcoma. The radical excision of the limbs is being retained, and the traditional amputation is being replaced. The local recurrence rate is about 5%. In many imaging examinations, how to choose the application is a new topic facing clinicians, which is related to the clinical diagnosis and treatment. Many scholars emphasize the echelon of imaging studies. Although X-ray can show the location of osteosarcoma, volume, bone destruction and osteogenesis reaction, but can not determine the extent of bone marrow invasion. Isotope scanning can
